  1. Respiratory System Review

  2. A Identify the structures labeled in the diagram. A – nasal cavity B – pharynx C – larynx D – trachea E – bronchi F – bronchioles G – lung H - diaphragm B C D E F G H

  3. A Explain the function of the respiratory system. To carry out gas exchange between the external and internal environment B C D E F G H

  4. A Identify the structure described. 1. Contain a ciliated mucus membrane 2. Voice box 3. Aids in breathing 4. Throat 5. Windpipe B C Nasal cavity and trachea D larynx E F G diaphragm pharynx trachea H

  5. Which is the correct sequence for the path of oxygen through the respiratory system? Nasal cavity Pharynx Larynx Trachea Bronchi Bronchioles Alveoli

  6. 1. The tubes that branch from the trachea are the 2. The dome shaped muscle below the chest cavity is called the 3. During swallowing, the air passage of the pharynx is covered by the 4. Alveoli in the lungs are connected to the bronchi by a network of tiny tubes called 5. Breathing is controlled by the chemistry of your blood as it interacts with the bronchi diaphragm epiglottis bronchioles carbon dioxide

  7. The diagram shows a rbc in part of a capillary. Area X is: • a nephron in a kidney • an alveolus in a lung • a villus in the small intestine • a cell in the liver

  8. Explain what happens to gases during gas exchange in the alveoli. Oxygen in alveoli diffues into capillaries (blood). Carbon dioxide in capillaries (blood) diffuses into alveoli.

  9. 1. Where are the vocal cords located in the body? 2. Breathing is an involuntary process controlled by the which part of the brain? 3.What prevents the trachea from collapsing? Where does the actual exchange of gases occur? During gas exchange where does the oxygen and carbon dioxide go? larynx medulla rings of cartilage alveoli O2 diffuses into capillaries. CO2 diffuses out of capillaries and into alveoli.

  10. The ______ is a long straight tube that carries air from the back of the throat to the lungs. trachea

  11. What structures trap foreign particles and bacteria in the nose and trachea? • pharynx        • epiglottis      • cilia        • trachea

  12. The order of air movement with in the lungs is best described as bronchioles to bronchi to alveoli       bronchi to bronchioles to alveoli trachea to bronchi to alveoli        bronchi to alveoli to bronchioles

  13. Where are the vocal cords located in the body? Larynx

  14. During swallowing, the air passage of the pharynx is covered by the epiglottis

  15. The FIRST branches off the trachea are called bronchi

  16. What prevents the trachea from collapsing? rings of cartilage

  17. The dome shaped muscle below the chest cavity is called the diaphragm

  18. Alveoli in the lungs are connected to the bronchi by a network of tiny tubes called • arterioles          • venules        • capillaries           • bronchioles

  19. Inside the alveoli, carbon dioxide and oxygen • are transported along microscopic tubules • are exchanged between air and blood   • are produced inside cells        • are exchanged for other gases

  20. Humans breathe more rapidly during exercise than before it because during exercise the blood contains • an increased level of oxygen • a decreased number of red blood cells • an increased level of carbon dioxide • a decreased amount of hemoglobin

  21. Breathing is an involuntary process controlled by the amount of ____ in your blood. carbon dioxide 

  22. Identify structures A, B and C. • Identify the process that occurs in the alveoli. • GAS EXCHANGE • 3. What happens to the blood pumped to the lungs? • IT BECOMES OXYGENATED BRONCHIOLE A CAPILLARIES C B ALVEOLI

  23. Identify the structure in the diagram. • What process occurs in this structure? • Identify the blood vessel surrounding this structure. • Identify gas X. • 5. Identify gas Y. • 6. Identify the process that causes the movement of gases. alveolus gas exchange X Y capillary O2 CO2 diffusion
